I ask about gender, because the main active ingredient in Tabernil Canto is male sex hormone (testosterone). This product is marketed as a "song enhancer" for male canaries, because it can trigger hormonal behaviors, like singing, in males. It is not intended for female birds and I would not expect it to be given to common quail.
Was this product reccomended to you? Why are you considering it for your quail?
Tabernil is a brand name and they offer a variety of similar looking products under that name. Be sure to double-check that you have the right product for your needs If you are looking for a liquid calcium and mineral supplement for egg-laying females, Tabernil Calcio is what you want.
